Fabricated (Welded)

4-ways valve

DN : 6"x4"x4"
Class : 2500 Lbs
Grade : 1.4541 (A321)

The technique of welded construction allows great flexibility in the design and construction of valves as well as a wide choice of materials. Our expertise in all-welded construction provides undeniable technical advantages, mainly linked to the use of semi-finished products such as rolled plates and bars, forgings and extruded tubes.
These advantages are:
-A very low general corrosion
-A very low rate of abrasion and erosion
-Excellent performance at high and low temperatures as well as to thermal shock
-Good resistance to mechanical and thermal fatigue
